Search Leasing Successor with 6 Zyl. Diesel

Hello, after many years BMW I changed to the Volvo XC60 2 years ago (significantly better leasing conditions). Now I want to drive a 6cylinder again and look for a successor for the Volvo. Unfortunately BMW (x3 30d or 40d) is in the conditions underground and so I am by chance on the Velar D300 hits, which I like very much. Now I read again and again about engine problems. How bad is the topic? I want to avoid standing in the workshop every few weeks. there are other problems with the vehicles? Leasing would be planned 36/15-20tkm p.a. and that should go without engine damage or bigger problems ?? g Peter
